This invention relates generally to paper feeding control devices andmore specifically to devices for controlling the printing of variousforms of records in a perforated card controlled tabulator.

an object of the invention is to provide feeding devices for handlingforms of statements, receipts, invoices, etc., so that printing isstarted at the proper position on each of a succession of such forms andif the number of items is greater than the number of lines on a form,printing will continue automatically at the proper position on thefollowing form.

Another object of the invention is to adapt the feeding devices forcontrol by a card controlled tabulator wherein the cards are arranged inroups. with means for feeding the record -sheet automatically from. formto form whenever card groups change. The extent of feed is automaticallycontrolled to put a form in place with its first line in printingposition regardless of the number of lines printed on the previous formwhen a group change occurs.

An object of the invention is to provide means for stopp ng the recordpaper for the printing of a first line at any desired location on aform, the feeding movement of the paper up to the first line of thefollowing form being resumed either immediately after the printing of asingle line on the form or after the printing of several consecutivelines and a total which may or may not be carried forward to the firstline of the following form.

An object of the invention is to provide record sheet form feedingdevices which are controlled by sets of perforations in the forms, therebeing one or two marginal perforations in one or both margins of eachform to control the starting and stopping of the sheet feeding devices.The perforations permit electric contact between adjustable brushes anda plate over which the live forms move, causing operation of a magneticclutch to disengage the drive to the platen roller. Subsequentconnection of the drive to the platen each group relating to a separateform,

on each form together with the printing of a total after the lastprinted line in the list: the machine functioning with automatic groupcontrol and a single perforation being provided on the side of eachform, the printing of the various items will occur each beneath theother, the functioning of the automatic control will cause the printingof the total below the last line of the list and then the paper is fedforward and the perforation on the following form will stop the paperwith the first line of print of the following form in printing position.

3. The printing of the items of any one group of cards on several formswith apro ressive total printed at the top of each one of them: themachine functioning with the automatic group control and the devicemtaking progressive totals, two perforations being provided on eachform, one on the left and one on the right, the right hand perforationof a form causing printing of a Progressive total on the preceding formbelow the last item listed on said form, then feeding is stopped by theleft hand perforation of the following form with the first line of printof the form in its printing position, the progressive total printed onthe preceding form being repeated on said first line of the followingform while the selection of a clearing operation will finally cause theprinting of the general total after the last line of the list on thelast form, following which the feeding of the paper will restart andwillbe stopped by the left hand perforation of the next form in positionto record the first items of a new group.

4. The printing of the total at the bottom of the form irrespective ofthe number of lines listed on said form: the machine functioning withthe automatic group control and two perforations beis obtained byenergization of another magnet I controlling the clutch whenever a lineis printed, a total is printed, an automatic group change occurs, or aprogressive total i printed.

By means of the devices f ggling the subject matter of the invention itis p ble to carry out the following form feeding operations:

1. The printing of a single line per form; the tabulating machineoperating in listing and a single perforation being provided on the sideof each form. feeding will occur after each line of print and the feedcontrol indiclum or perforation of each form will stop the followingform with its first line in printing position.

2. The printing of a variable number of lines ing provided on the sideof each form, the functioning of the automatic control will cause thefeeding of the paper which wili be stopped by the first perforation ofthe following form for the printing of the total at the bottom of thefirst form considered and said impression of the total causing a furtherfeeding of the paper which is stopped by the second perforation of thefollowing form with theflrst line of said last form in printingposition.

5. Hie printing of the items of a group of cards on several forms withor without a total on each and without carrying forward a progressivetotal from one form to another: two perforations being provided on eachform, one on the left and the other onthe right, the perforation on theright hand side of the following form will initiate the printing of thetotal of the items listed on the form considered even if, at thismoment, the

functioning of the automatic group control does not occur, the feedingof the paper restarting automatically after the printing of said totaluntil.

it is stopped by the left hand perforation on the form which comes afterthe following form which has just been referred to, with the firstprinting line of said following form in printing position.

The foregoing and other objects of the invention will become apparent asthis specification continues with reference to the drawings forming partof the disclosure.

The feeding devices are incorporated in a card controlled machine of thekind disclosed in United States Patent No. 1,978,617. In such machines,record cards C (Fig. 11) are sensed to control accumulating and printingoperations. These cards are arranged in groups according to groupnumbers perforated therein so that a series of related items may beadded to form a total amount of the group. The cards are passed throughthe machine in succession and automatic group controldevices compare thegroup numbers on consecutive cards so that a group change may bedetected. When such a change is detected, a total printing operation isinitiated and the accumulator is reset.

The tabulator printing mechanism is shown in Fig. l2. There it is seenthat a listing shaft I65 drives the mechanism during listing operationsand a totaling reset shaft J66 drives it during total taking operations.The machine is provided with a number of can operated contactsidentified by the prefix letters L and P, the former operated by cams onshafts that operate only during listing, and the latter operated by camsthat rotate only during total taking as in Patent 1,976,611. The recordstrip R is held around a platen 2 and there receives the printingimpressions. A printer control magnet PM is energized at a differentialinstant accordin to the time of sensing a perforation in the record cardor the time that an accumulator controlled total contact is closed.-Moving in synchronism with the other tabulating mechanism is a type bar2 I2 formed with notches 2I6 that are moved in succession past a stoppawl 2 l1. when magnet PM is energized it attracts an armature lever 22lto which is attached a call wire 220 connected at the opposite end to alatch 2 Ha. for releasing p wl 2". Thus the type bar 2l2 is stoppedspecial cam Fig. 12.

differentially by the pawl engaging in one of the notches 216; the barstopping between a hammer 224 and platen 2 to place at the printingline. type 2l8 corresponding to the value of the perforation or totalamount sensed. For a more detailed understanding of the structure andoperation of the tabulator, reference may be made to the patentidentified hereinbefore.

The line spacing mechanism is shown in Fig. 11A where a shaft 208 isshown as having a space operating arm 262 secured to one end thereof.Shaft 20B is rocked on every printing cycle of the machine by the camson shafts I65, I55,

Arm 262 (Fig. 11A) is rocked therewith and carries a pin 263 which isadapted to engage a member 26! integral with an arm 2B5 rotatable abouta fixed pivot 286. The arm 265 is connected by a link 251 to an arm 268which has a pin and slot connection 269 with an arm 212 pivoted on thesupporting axis of the platen.

Arm 210 carries the spring pressed pawl 21! which is adapted to engage aratchet 212, Fig. *6, for driving the platen 2. Clockwise rocking ofshaft 228, Fig. 11A. accompanied by the upward movement of the printingcross-head will rock member 264 and arm 26! in a counterclockwisedirection to cause actuation of the ratchet 212 in a clockwise directionand effect paper spacing before the printing hammers are tripped.

Arm 285 has secured thereto a further member 212 connected by a link 214to an arm 215 loosely pivoted on the shaft 202, A pin 215, projectingfrom a mutilated gear 211 secured upon the total shaft ISO, is adaptedto rock arm 215 during total taking operations to eflect an additionalspacing operation of the platen. Pin 216 is so located that it actuatesthe paper spacing mechanism after the printing operation.

As shown in Fig. 6, the record forms are on a strip R which is unfoldedout of a magazine I. passed around the platen roller 2 and then returnedto a receiving magazine 2. The forms may be separated by printed dottedline across the strip, but perforated lines should be avoided becauseelectrical contact is liable to be established therethrough.

In Figs. '1, 8, and 9 are shown the mechanisms by which platen 2 isturned to feed the strip. The platen may be turned under control of thelisting shaft I85 or the reset shaft iii, the former turning onerevolution on each listing cycle and the latter revolving on each totalprinting cycle. The shafts are connected to the platen shaft 2 through achain 6 and three gears I, I and 9. The mechanism is mounted between apair of side plates S and S fixed to the base B.

Fixed to the shaft IE6 is a ratchet wheel i0 engaging a pawl ll pivotedon a gear I! loosely mounted on the shaft. A spring l2 tends to keep thepawl in engagement. Gear l2 meshes with a gear ll loose on shaft I85 butcarrying a pawl l5 which engages the teeth of a ratchet wheel I'l keyedon said list shaft I65. A spring l6 holds the pawl l8 against wheel ll.Gear II is formed with a sleeve 4 carrying a sprocket wheel it aroundwhich passes the chain I which also meshes with a sprocket wheel isloosely mounted on a shaft 5 which is keyed to the feeding drive gear I.The sprocket l9 may be connected to the drive gear I, gears 8 and 9, andplaten 2, through a friction clutch comprising a friction disk 20 whichis fastened on the sprocket and a slidable keyed sleeve 20 which may bepressed against disk 22 by spring l9 or moved away therefrom by electriccontrols about to be described.

It isapparent from the foregoing that when? clutch 20-20 is engaged.paper feed roller I is driven either by list shaft I65 or by reset shaftI66 according to which of said shafts is in rotation. If, for instance,it is the resetting shaft which is in operation, the drive of theroller-will occur through ratchet wheel I driving pawl II andconsequently gear it in its rotation, said gear l3 driving gear ll thepawl of which will slide idly over ratchet wheel I! which is stationary(see arrows in Fig. 1 showing rotational direction of gears II and It)and through sprocket wheel ll solid with gear I and driving chain 0,sprocket 'wheel II and the series of gears I, I, and S. If on thecontrary it is listing shaft I" which is in operation, it is ratchetwheel I! which, through pawl II, will drive gear ll, the rest of themovement continuing up to roller 2 in the same manner as in the othercase: the rotation of gear It will actuate gear II, the eii'ect of whichwill simply be to cause pawl II to slide over the teeth of thestationary ratchet wheel II.

In other words. paper feed roller 2 rotates either through shaft I" orthrough shaft I" each time clutch 2l-2l is in engagement. An engagingelectromagnet 2| makes it possible, by means of an associated armature22 pivoting at to control eng ing sleeve II by a lever 22' arranged tobring it against disk II to determine clutch engagement. Magnet 2i tripsthe latch connections (Fig. 6A) which normally hold lever 28' and sleeve20' (Fig. 9) out of clutching relationshln, against the tension ofspring It. Lever 22' has an end which fits into the groove on sleeve20'. and pivots on a vertical stud 2| (Fig. 'I) so that a block 28thereon is in the path of a depending iinger its on armature 21. Whenthe armature is attracted, finger as moves to the right (Fig. 6A) out ofthe path of block II and thereby releases lever 22 (Fig. 9) so that itmay be rocked in a counterclockwise direction (clockwise in Fig. 6A) byspring ll to press sleeve 20' against disk 20 in driving relationship. Adisengaging electromagnet 2| (Figs. 7 and 8) operates in an opposite waythrough an armature lever 2| cooperating with'lever 22' to shift sleeveII away from disk II, compress spring II and relatch lever 21 and blockII behind armature finger its and thus stop the rotation of platen 2 andthe feed of the paper strip. Lever 24' pivots on a rod 24b and carriesan adjustable projection 28a pushing against the end of lever I! so thatit may be rocked in a clockwise direction (Fig. 9) and relatched asshown in Fig. 6A.

The devices for controlling the energization of magnets II and 2| whichmake it possible to engage or disengage the clutch for controlling theplaten drive will now be explained.

Energization of engaging magnet 2| is obtained either under control ofthe print devices when listing, operation of the automatic group controldevices, the means for printing a progressive total, the actuation ofthe major, intermediate or minor total control, the operation of classselection devices by special cards, or finally through the action of amarginal perforation provided on one side of a record form incooperation with an adjustable brush 26 (Fig. 6) adapted to contact aconducting plate 2! when a start indicium or perforation appears underthe brush, said plate 21 serving at the same time as a guide for thepaper.

Paper ieeding is stopped in order that a single line may be printed, orthe first line as an item or a progressive total may be printed, ortotals may be impressed in the desired position on a form, any of theaforesaid controls being produced by devices including an adjustablebrush 2! cooperating with the left side of strip R and contacting withplate 21 at times determined by the differential placement of marginalstop indicia or perforations in the forms.

A third adjustable brush 28 is out of line with the perforations in thestrip because it is provided merely to sense the passage of the end ofthe record strip It. When the end passes the brush 2!, contact withplate21 is established and a means is activated to stop the tabulator so thatno more cards are fed.

The electrical connections about to be considered make it possible tocontrol the energizatlcn of engaging magnet 2| and disengaging magnet 24and consequently the engagin or disengaging of the paper feed device.These connections not only include the sensing devices cooperating withthe strip, but also modifications in the wiring of the tabulatingmachine in order to obtain the control of printing in any desiredposition on a form.

Reference may be made to Fig. 10 where is shown the electrical stripsensing'controls that are connected to printing tabul ator so that itmay fulfill the various requirements indicated hereinbefore. As seen inthis diagram, brush II, which controls to stop the feeding of cards whenthe paper strip comes to an end, is connected by a wire 29 to a stoprelay 10 which acts, when energized, to open contacts lib (Fig. 10A) inseries with the stop key contacts I. of the tabulator. On wire is isalso located a hand-controlled switch 31 which is closed when'it isdesired to bring into action the sensing devices forming part of thesubject matter of the in vention. Plate 21, with which brush it makescontact when there is no more paper available for passing over printingroller 1, is connected to wires ll, 84 and 62 leading to an oppositemain line ill and in the path of which is positioned a hand-operatedswitch 35 which is closed when it is desired to utilize the paper feeddevices which form the subject matter of the present invention.

It should be noted that main lines I, "I are connected to the tabulatorwiring in Fig. 10A and are energized when a switch P8 is closed toconnect to the power source. It should likewise be noted that theelectric connection shown at 21' in Fig. 10 is merely a diagrammaticindication, said connection being obtained in actual practice byconducting plate 21 itself. From the foregoing it will be seen that whenthe paper passes over plate 21 to pass round printing roller 2, itinsulates brush it from platejl; consequently relay 30 is not energizedand its contact 30b (Fig. 10A) does not break the energizing circuit ofthe engaging electromagnet of the card feed device and said cardscontinue to pass through the machine unless other operations (automaticcontrol, stop key operation, etc.) stop said feed in the usual manner.0n the contrary, if ,there is no more paper passing under brush II, thatis to say, if there is no other form ready to pass over roller 2 forprinting, brush 28 makes contact with plate 21 and the following circuitis set up in consequence: line I", switch ll.

avoid sparking on the breaking relay 3|), wire 29, brush 2!, plate21-21, wire 33, switch 35, wires 54 and 62, and line 33L Consequently,relay 30 is energized which causes, as hereinabove indicated, thebreaking of the energizing circuit of the engaging electromagnet of thetabulator card feeding devices.

When it is energized, electromagnet 30 also controls the breaking ofcontact 30a which is normally closed. the effect of which, when there isno more paper passing on plate 21, is to suppress all action of thepaper feeding devices.

One circuit which is influenced by the opening of contact 30a is thecircuit containing left hand brush 25 and the disengaging magnet 24 forstopping the paper feed mechanism. This brush 25 is provided to sensethe appearance of a left hand marginal perforation in the paper andthereby energize magnet 24 by means of a circuit including line 33!,wires 82 and 64, switch 35, wire 33, connection 21', plate 21, brush 25,wire 31, magnet 24, wire 38, contact 300, wire 2!, switch II and line330. A progressive total control circuit is also influenced by operationof contact 20a, because it follows a path through line 330, switch 3|,wire 29, contact Illa, wire 28a, bus bar 39, wire 4|, progressive totalrelay 42, progressive total magnet 43, wire 44, contact 12b, plug wirefrom TI to 16, wire 15, brush 26, through a right side marginalperforation to plate 21, wire 33, switch 35 and wires 64 and III to lineiii.

The disengaging magnet 24 is in addition connected, by one of itsterminals, to a wire 41 leading to one terminal of disengaging relay 48,the other terminal of which is connected, by a wire 49. to bus bar 39.Said magnet 24 is connected, through its other terminal, to a wire 50leadin to one of the terminals of engaging magnet 2|. Disengaging relay4!, when energized, closes a contact 48:: one of the terminals of whichis connected to wire 41 and the other terminal of which is connected toa wire 8| connected to a contact 24a. which is normally closed (thebreaking of which is controlled by the energizing of magnet 24) and to awire 52 leading to plate 21. A condenser 53 is generally provided as ashunt in relation to contacts 48a and 24a in order to of said contacts.

One of the terminals of engaging magnet 2| is connected to wire 54; itsother terminal is connected to a wire 54 leading to a twin plug socket55 which can be electrically connected by means of plug wire connectionseither to socket 56 relative to the minor control, or to a socket B, orto both of these.

Socket 58 is connected, by a wire 59, to a cam contact L33 which isadjusted to close for a moment between the passage of the cards andafter the printing of each line, said cam contact being moreoverconnected, by a wire ill, to one of the terminals of a contact 61b(controlled by electromagnet 81 positioned on the minor control circuit,as will be seen later), the other terminal of which is connected by awire 42, to line HI and by a wire 64 to switch 35; said contact 61b maybe short-circuited by a switch 65 which is closed when the machine isoperated only for listing and which is opened when the machine isoperated with automatic control. Socket it of the minor control isconnected, by a wire 66, to a contact 61a which is closed when magnet61, which controls it, ceases to be energized (said magnet beingpositioned as will be explained later, in the relay circuit of the minorcontrol) and which is connected, in addition, by wires 88 and 68a to acam contact Pll designed to be closed after total printing, said camcontact being connected by awire B9 to line I.

A circuit through wire 68a includes a contact 430 (the closing of whichis controlled by the energizing of coil 43 hereinabove mentioned), awire ll, one winding of double wound relay l2 and a wire H which leadsto one of the terminals of contact 30a and to wire 38. Said double woundrelay [2, the second winding of which is positioned in another circuitleading from bus bar 39 to wire 5|, controls a contact 120. which closeswhen the first mentioned winding of the relay in question is excited;said contact is placed on the same circuit as the second winding ofdouble wound relay 12 inserted between wires 13 and 14.

Right hand brush 2G is connected, by wire 15, to a double socket Iiwhich may be connected, by means of a plug wire connection, to a socket11 which is connected to a contact 12b, the breaking of which iscontrolled by the energizing of double wound relay 12, said contact 12bbeing arranged in series relatively to coil 42 of the relaycorresponding to the progressive total and to coil 43 mentionedhereinbefore.

When it is desired to control the engagement of the paper feed by meansof a perforation swept by brush 25, the socket I6 is connected by a plugwire to a socket l1 wired to a relay 43', said relay being itselfconnected by a wire and a resistance to bus bar 39. When energized,relay 43' closes a contact 43'd, one terminal of which is connected tocoil 43' while the other terminal is connected by a cam contact L33(adjusted to open at the same time as cam contact L33) and by wires toplate 21. Coil 43, when energized, likewise controls the closing of a,contact 43'!) shunted in relation to the combination of sockets 55 and58.

Moreover, according to the invention, in the customary circuit of stopkey contacts 15' (see Fig. 10A) is positioned a contact 301) which isnormally closed but which opens when stop relay all (see Fig. 10) isenergized, that is to say, when brush 28 makes contact with plate 21, inother words, when there is no more paper to be passed over printingroller 2; the breaking of said contact 30b breaks the circuit of thestop contacts in which is also positioned the usual engaging magnet 22!of the card feed device as well as start relay 18 which starts and holdsthe energization of said magnet. When there is no more paper to besupplied to roller 2 the card feed device is therefore disengaged andthe card feed of. the machine is automatically stopped in consequence.

In the same circuit as the stop contacts 16' is positioned a three bladecontact 4311 which normally occupies the position shown in Fig. 10A,with its upper contacts normally closed in series with start relay 18holding magnet 22! engaged, but the central blade of which is moved toopen upper contact 43b when a feed control magnet 43 is energized. Thecircuit which initiates the effectiveness of the card feed clutch magnet22f while the tabulator is operating, may be traced through line330,'cam contact Pl, magnet 22). relay 340, relay 1!, switch 353, camcontact P2, card contact LCLa, stop key contact 16', contact 30b, uppercontact 43b, lower contact 3380 closed by control magnet 82, and line33!. This circuit is again initiated if the upper contact 43b is heldclosed. Said contact 431) has been provided in order to deenergize relayIll which would otherwise tend to hold the energization of the card feedengaging magnet between the printing of one progressive total and theprinting of a carry forward of said total on to another form. Magnet 43is energized, to open upper contacts 43b when brush 2B encounters amarginal perforation, in order to stop card feeding and in order 5 toprevent the feeding of cards between said two consecutive printings ofprogressive totals, as will be seen from what follows.

Magnet 42 related to the taking of a progressive total, also causes,when energized, the closing of a contact 42a shunted in relation tocontact P3 (see Fig. 10A) when switch 19 is closed, said switchbeingclosed when it is desired to print on the forms, accounting itemswith progressive totals. The first progressive total is initiated bydirecting a circuit through the auto reset relay 34! which in turnactivates the reset clutch magnet 80 and the motor RM. The circuitthrough relay 348 includes line 330, contact 420, switch l9, relay 348,cam contact L3, switch 346, lower 20 contact 43b (closed because relay43 is energized at the same time as relay 42) lower contact 338a andline III. Relay 348 then closes contact 348a to energize magnet 80 andestablish a holding circuit. The holding circuit passes through line at,contact P3, magnet 348, contact 348a, to line "I. At the end of thecycle, contact L4 closes completing a circuit from line 330, contact p3and 384e, clutch magnet 80. contact L4, contact 248a and line "I. Magnet80 then operates a lever to close contacts 281 in shunt around contactP4. Then the reset motor RM and the zero control magnet 350 areenergized and a total printing operation is effected, but resetting ofthe accumulator is prevented. 'A second cycle of totaling is induced bythe continued closure of contact 420. Said contact 42a remains closedduring the time relay 42 is energized, said period of energizaticn beingregulated by the duration of the closing of cam contact Pia (see Fig.10); 40 the setting of the cam of said contact is such that magnet 42remains energized sumciently long and that contact 420 may inconsequence be closed long enough to carry out two successive totaltaking cycles (whereas the duration of the 5 closing of P3 is such thatnormally a single total taking cycle is eflected through the magnet IIIwhich controls engagement of the total print mechanism with the resetmotor RM) making it possible. in the case of progressive totalselection,

t to print said progressive total and then to print the carry forward ofsaid total on the following iorm.- Near the end of the first totalprinting cycle, feeding of the record sheet is initiated by themomentary closure of contacts Pl I, Fig. 13, but immediately beforethis, contacts Pia open momentarily, and close again before brush 26 isinsulated from plate 21 by the sheet which starts to move. Therefore,magnet 42 is again energized to close contacts 42a and initiate a sec-0nd progressive total printing cycle. Near the. end of this secondcycle, contacts Pia again opeh" and close, and this time magnet 42becomes deeners'lzed because brush 28 has been insulated by the shiftedrecord sheet.

The closure of contacts 420 serves to make magnet 80 effective longerthan usual. When contacts P4 open at the end of the total print cycle,the reset motor circuit is not broken as it is usual- 1y, instead ashunt comprising contacts 2" held closed by magnet 80 maintains resetmotor operation for another cycle.

As shown in Fig. 10A, a magnet 6l.is inserted in the circuit of relay llof the minor control which also includes relay l2 controlling thetabulating motor. The excitation of magnet ll causes the breaking ofcontact "a hereinabove mentioned (see Fig. 10) and also opening ofcontact 61b. In addition, relay ll of the minor control, controlscontact Ila. the blade of which is connected as usual to bus bar llleading to main line I",

which components exist in the tabulating machines already known. ContactIla assumes the position shown in Fig. 10A when relay 8! of the minorcontrol is not energized. Instead of using coil BI and the associatedconnections in the minor control circuit, similar connections may beinserted in the major control circuit, if such controlis desired.

In order to prevent resetting of the accumulators while totals areprinted as at I and I". Fig. 3, a switch 84, Fig. 10A, is provided toopen the connections leading to the reset magnet I82, thus preventingresetting of the accumulators. This switch 94 when opened causes thetaking of progressive totals, after which it may be closed to allowmagnet I82 to be energized fora clearing total.

The same progressive totaling form of control 5 may be obtained inanother way with switch 94 held closed. Then the dial switch is set at"Prog," but turned to Min" after progressive totals have been recorded.The auto restart switch 353 may be opened so that the machine is stoppedafter each progressive total printing cycle so that the operator canturn the dial switch to "Min" and press the reset key whenever hedesires to take a clearing total.

The diagram of the circuits and of the moditlcations which are made inthe electric connections of the tabulating machine having been describedhereinbefore, the operation of the devices which form the subject matterof the invention will now be explained with reference to various typicalcases such as those indicated in the ob- Jects of the invention.

Assuming first of all that it is desired to print on each form (aninvoice for instance) a single line from each of a series of cardspassing through the machine operating in listing, each line of printcontaining the particulars of a single card on each form and the feed ofthe paper having to occur between each line printed. This is the caserepresented in Fig. 1. In said figure, the arrow indicates the directionof travel of the paper forms. In the case considered, a singleperforation on the left hand side is necessary on each form this is theperforation shown at a. In addition, special switch 65 (Fig. 10) isclosed (in addition to switches Ii and 3B which are always closed whenit is desired to operate the feeding devices) and a plug wire connectionis made between socket 58 and socket 88. Finally, the position of theleft hand brush 2! (see Figs. 6 and 10) is so adjusted that perforationa shall appear under said brush when the location for printing on thepreceding form is beneath the printing ribbon against which the typeimpinges. For instance, referring to Fig. i, the adjustment of theposition of brush 25 is such that when perforation a is beneath brush24. line 1 on which the printing of the previous form is to take place,is in the printing position.

Referring now to thediagram of the circuits represented in Fig. 10. itwill at once be seen that as soon as the line of print I has beenprinted, engaging magnet 2i of the paper feed device is en-- ergized bythe establishing of the following circult: line 830, switch 3|, wire 20,contact 30a, wire 38. wire 50. magnet IL'WN i4, socket Ii,

'group of cards, the

plug connection leading to socket 58, wire 55, cam contact L33 closed atthis moment, wire 55, switch 55, wire 52, and line 331. The setting upof this circuit occurs due to the closing of contact L33 which is soadjusted as to close for a moment between the passage of the cards andafter the printing of the line. The paper feed device being thus engagedafter the printing of line 1, the paper travels forward until saiddevice becomes disengaged, which is brought about by means ofperforation a, the position of which is such that it causes the stoppageof the paper at line 1' (see Fig. 1). This disengagement of the paperfeed device is obtained by means of magnet 24 which is energized longenough to cause said disengagement. The energization of magnet 24 issustained momentarily by an impulse carrying circuit set up by a relay45 which is energized at the same time as magnet 24 when sensing brushencounters a perforation a. When perforation a arrives under brush 25the following circuit is established: line 335, switch 3|, wire 25,contact a, wire a, wire 45, relay 45, wire 41, wire 31, brush 25, plate21-21, wire 33, switch 35, wires 54 and 52, and line 33L At the sametime, magnet 24 is energized by a circuit through line 330, switch 3|,wire 23, contact 30a, wire 35, magnet 24, wire 31, brush 25, plate21-21', wire 33, switch 35, wires 54 and 52 and line 331. Then, withboth relay and magnet 24 energized, the relay closes contact 4511 andthe magnet opens contact 2411; but the contact operation is notsimultaneous, because contact 450. is quick to close and contact 24a isslow to open, therefore there is an instant that magnet 24 is energizedindependently of the brush circuit. Energization of relay 45 during theshort period that the perforation passes under the brush, quickly causesthe closing of contact 4501 which is coupled to it and the setting up ofthe following impulse circuit for momentarily holding the energizationof the disengaging magnet 24; line 330, switch 3|, wire 23, contact 35a,wire 35, magnet 24, wire 41, contact 4541, wire 5|, contact 24a, wire52, plate 21-21, wire 33, switch 35. wires 54 and 52, and line 33!.Consequently, magnet 24 is energized sufficiently long, even after theperforation is no longer beneath brush 25, for the paper feed device tobe declutched; in other words, perforation a has caused the stoppage ofthe feed of the paper with line 1' in the printing position so that theparticulars corresponding to the next card may be printed at this spot.The contact 24a is soon opened by the energized magnet 24 and then bothrelay 45 and magnet 24 are deenergized because brush 25 is separatedfrom plate 21 by the record paper. Contact 240 finally resumes thenormal closed position when magnet 24 is deenergized.

It will now be assumed that the machine is functioning with automaticgroup control and that on each printed form it is desired to print avariable number of lines corresponding to one printing l f the totalappearing beneath the lines previously printed on the form. In thiscase, represented in Fig. 2, a single perforation is still necessary,namely, perforation a on the left hand side of each form. In addition,switch is open and a plug connection is made between socket 55 andsocket 55 corresponding to the minor control.

Engaging magnet 2| in the example under consideration becomes energizedafter the printing of the total on the closing of cam contact PM (seeFig. 10). the cam of which is so adjusted that the contact closes afterthe printing of the total. The energizing circuit is as follows: line330, switch 3|, wire 29, contact 30a, wire 38, wire 55, magnet 2|, wire54, socket 55, socket 55, contact 51a closed at this moment owing to thedeenergization of the control relay 51, wire 65, wire 55a, contact Plwire 55, and line 331. After energization of magnet 21, the paper feedsforward until perforation a stops the paper with line l of the precedingform in the printing position (see Fig. 2). The operating circuits ofdisengaging magnet 24 are in every way similar to those described inconnection with the preceding case and need not be described anew. Saiddisengaging magnet 24 functions, as has been seen, owing to the passageof perforation a under brush 25.

It will now be assumed that the list of items of one group of cards istoo long to be printed on a single sheet and that it is necessary to useseveral forms with a progressive carry forward on each form. In suchcase, several successive forms will be completed, the last formcorresponding to a group of cards under consideration comprising thefinal general total positioned below the last line of accounting itemsplaced on the list. As seen in Fig. 3, it is necessary to employ twoperforations, one located on the left, perforation a, working incqoperatio'n with brush 25, and the other located on the right,perforation b, working in cooperation with brush 25 (see Figs. 6 and 10)Perforation a is intended to stop the feed of the paper so that thefirst line of the preceding form shall be in the printing position.Perforation b is utilized to cause the stopping of the paper and theprinting of a progressive total at the bottom of the preceding form. Theright hand brush 25, which cooperates with perforation b, should beadjusted in such manner that it comes into contact with perforation bwhen the line before the last line of the preceding form is under theprinting ribbon. Left hand brush 25 will be adjusted as in the precedingcase.

In addition, the connections to be made in Fig. 10 are as follows;switch 55 open, a plug connection made between socket 55 and socket 55,and a plug connection made between socket 11 and socket 15. Whenperforation 1: comes under brush 25, the following circuit will beestablished: line 335, switch 3|, wire 23, contact 30a, wire 350, busbar 33, wire 4|, relay 42, coil 43, contact 12b normally closed, socketl1, plug connection leading to socket 15, wire 15, brush 25, plate 21,wire 33, switch 35 closed, wires 54 and 52, and line 33!. Consequently,progressive total relay 42 is energized; a holding circuit is moreoverestablished by contact 43a which is closed owing to the energizing, ofcoil 43. This holding circuit, which continues from coil 43 up to line33! and which includes contact 430, wire 45, cam contact P50. and wire45, maintains the progressive total relay 42 energized even afterperforation b is no longer under brush 25. The duration of the closingperiod of contact PM is adjusted in such manner that magnet 42controlling contact 420. of the progress ve total circuit (see F g. 10A,with switch 15 closed when the device is operated with a taking ofprogressive totals) makes it possible to carry out two successive totaltaking cycles and consequently two printings of the progressive total,one at the bottom of one form and the other on the first line of thefollowing form as explained hereinbefore. Upper contact 43!) (see Fig.10A) controlled by coil 43 (see Fig. 10) opens to deenergize relay 13for disengagement of the card feed device and thus stops card feedingand prevents the feeding of cards in the machine between the twoprlntings of the progressive total at the end of one form and at thebeginning of the following form.

In addition, the energization of coil 43 causes the closing of contactno and in consequence the energization of magnet 2| for engaging thepaper feed device after the printing of the progressive total owing tothe establishing of the following circuit: line 333, switch 3|, wire 29,contact 30a, wire 38. wire 50, engaging magnet 2|, wire Ha, wire ll,contact 43c, wire 33a, cam contact Pl I, wire 83, and line 33 I. Thus.after the printing of the progressive total at the bottom of the form at1', said printing occurring owing to right hand perforation b on thefollowing form, engaging magnet U is energized and the sheet of paper isfed forward until it is stopped by perforation a of the form which isbehind it, the position of brush :5 being adjusted in such a way thatsaid perforation a stops the form preceding it with line 1" in printingposition. The circuit through which disengaging magnet 24 becomesenergized and the sheet of paper is stopped when line I" is in theprinting position (the progressive total being carried forward to thisline owing to the duration of energization of magnet 42) will be throughbrush 23 the same as in the previous instances. Therefore, it is notnecessary to describe it anew.

During the first progressive total printing cycle, brush 23 (Fig.projects through perforation b and maintains relay 42 energized eventhough cam contact PGa opens for a short time near the end of theoperation. At the end of this first cycle, paper feeding takes place andthe brush 26 is insulated, but contact Plic has again closed to hold theenergization of relay 2. 0n the second progressive total printing cycle,after printing has occurred, contact Pia again opens and then relay 2 isdeenergized. Contact 420 (Fig. 10A) then opens to deenergize relays 33and 343, thereby causing contacts 231 to open, and later in the secondcycle, contact Pl opens to deenergize the reset motor RM.

On the form coming next (which form commences at line I" by the carryforward of the progressive total (see Fig. 3) will be inscribed otherrelated accounting items and, if there is no change in the group ofcards, a progressive total will be printed at the bottom of the form, ashas previously been explained. 11, on the contrary, a minor or majorchange of group occurs in the interval, the total will be printed andthe paper will feed after the printing of said total up to the firstline of the following form exactly as in the case previously considered.The last mentioned total will also be a progressive total unless theoperator intervenes to close switch 93, Fig. 10A, or shift the dialswitch to Min. But, in order to avoid the reenergization of relays 42and 43 in this latter case by the passage of the perforation in front ofthe right hand brush during the feed after the printing of the major orminor total, provision has been made. as indicated in the previousgeneral description, of double wound relay 12. the purpose of which isto break contact 12?) which is situated in said circuit of brush 33.which breaks the circuit of progressive total relay 42 and of coil 43.The energlzation of double wound relay I2 is caused by the followingcircuit: line 333, switch 3|, wire 23. contact 30a, wire ll, doublewound relay 12, wire Ila, wire 54, socket ii, plug connection leading tosocket 36, contact 31c closed owing to the operation of the groupcontrol, wire 33 and wire 3311, cam contact Pi i, wire 33, and line III.A holding circuit for relay I2 is established by the closure of contact12a.. The circuit may be traced through line 330, switch 3 i, wire 23,contact 30a, wire 33a, bus bar 39, wire I4, holding coil 12, contact12c, wires 13 and 5|, contact 24a. wire 32, connection 21', wire 33.switch 33, wires 34 and B2, and line 33L This circuit is maintainedduring feeding until con tact 24a is opened by energization of magnet 24brought about when brush 2i encounters a control perforation.

It will now be assumed that the total is to be printed at the bottom ofthe form irrespective of the number of lines listed on said form. Thisis the case represented in Fig. 4. Under these conditions it isnecessary to provide two perforations on .the left hand side of eachform and to establish a plug wire connection between double socket $5and socket 58 and another plug wire connection between double socket 55and socket 56, switch 65 being open as before. In this manner, twofeeding operations of the paper may be obtained; one feed which occurswith the functioning of the major or minor control and which is arrestedby the first perforation c of the next form for the printing of thetotal at the bottom of the form (referring to Fig. 4, perforation 0'will stop the paper with line I of the preceding form in the totalprinting position) and a feed which occurs after the printing of saidtotal and which is arrested by perforation a of the form (for instance,if Fig. 4 is considered, perforation a will stop the pap r, after theprinting of line 1, with line i in the printing position).

Distance A (Fig. 4) between the two perforations on any one form mustobviously be equal to distance B included between the line on which thetotal is printed and the first line of the following form as willreadily be understood.

As already explained, it is necessary that after the printing of thelast line listed on a statement, and prior to the printing of the total,a forward feed should occur, that is to say that engaging magnet 2|should be energized, and this occurs through the following circuit: line330, switch 3 I, wire 23, contact 30a, wire 33, wire 50, magnet 2 I,wire 54, socket 55, plug connection leading to socket 53, wire 39,contact L33, wire 60, contact 31b, wire 62 and line 33!. It has beenexplained that contact L33 is adjusted in such manner as to be closedfor a moment between the cards and after the printing of each line; alsothat contact no closes on account of the functioning of the major orminor automatic control; a feeding operation therefore occurs after thefunctioning of the control and prior to the printing of the total. Saidfeed is arrested by the first perfora tion 0 of the following form whensaid perforation arrives beneath brush 25 to energize the disengagingmagnet 24 and at the same time enersizes the sustaining relay magnet 43.Then the following circuit is established: line 330, switch 31, wire 23,contact 30a, wire 38a, wire 49, magnet 43, wire 41, wire 31. brush 25,plate 21-41, wire 33, switch 33, wires 34 and G2 and line 33L Relay 43being energized, contact 43a closes and the following circuit isestablished: line 330, switch 3!, wire 29, contact 30a, wire 38, magnet23, wire (I, contact a, wire 5|, contact 24a, wire 32, plate 21-41, wire33, switch 35, wires 64 and 32 and line 33L The paper is thus stoppedjust before printing occurs with the last line, 2, of the form inprinting position,

The total is printed and immediately after, a

further feeding operation occurs owing to the onergization of engagingmagnet 2| due to the establishing of the following circuit: line 330,switch 3|, wire 29, contact 30a, wire 38, wire 58, magnet 2i, wire 54,socket 55, plug connection leading to socket 56, contact 51a, wire 68,wire Gila, cam contact PI I, wire 69, and line 331. The adjustment ofcam contact PH is such that said contact closes after the printing ofthe total. This further feed of the paper is then stopped by the secondperforation (I'Of the form so that said paper is stopped with first line1' of the form in the printing position. The circuit for stopping thefeed of the paper is the same as in the preceding cases: it is thereforenot necessary to describe it anew.

Finally it will be assumed, in the last example, that it is desired toprint the items of a group cf cards on several forms. This is the caseshown in Fig. 5. It will be seen that it is necessary to employ twoperforations in this case: perforation a positioned on the left andcooperating with brush 25, and perforation b positioned on the right andco-operating with brush 26. Perforation 17 makes it possible to obtain apaper feeding operation after the printing of the last line of the form.Perforation a is utilized to stop the feed of the paper after the feedsubsequent to said printing, with the first line of the form in theprinting position. For the continuation of item printing it is necessaryto establish the following connections: close switch 65, plug connectionbetween socket 55 and socket 58, plug connection between socket I6 andsocket 11'. Under these conditions, when perforation b arrives beneathbrush 25, the following circuit will be established: line 330, switch3|, wire 29, contact 300, wire 38a, bus bar 39, coil 43', socket I1,plug connection leading to socket 16, wire 15, brush 28, plate 21, wire33, switch 35, wires 64 and 52 and line 33L As coil 43' is energized,contact l3'a will close, maintaining the energization of coil 43'through the following circuit: bus bar 39, coil 43', contact "'11, camcontact L33 closed at "1 and held c osed until after printing, wire 33,switch 35, wires N and B2 and line 33L The energization of coil 43determines the closing of contact 43'!) which establishes the circuit ofengaging magnet 21 and therefore causes the feeding of the paper whencontact L33 closes, that is to say immediately after the printing of theline. Should the account call for the printing of the total before theend of a form is reached, then sheet feeding is initiated after totalprinting by the energization of engaging magnet 2i through a circuitincluding line 330, switch 3|, wire 29, contact Illa, wires 38 and 50,magnet 2|, wire socket 55, plug wire to socket 58, contact 61a, wires 68and 88a, cam contacts Pl I, wire 59 and line Ill. The feeding operationwill be arrested by perforation a so that the first line of thefollowing form will be in the printing position. The termination of thepaper feed under these conditions occurs in the same manner as in thecases previously described, making further explanation unnecessary.
